'SPECIFICATION forming parc of Letters Patent' No.' ns1 ,i samenle-'gust1e, 1892'.- f Appumion'sna December 13,1890. sen'n no. 374,642. damobiel.) l f 4To all whom it may concern 'Be it known that I,JOHN S.RSH, a citizen A of .the United States of America, residing at Denver,inthe county of Arapahoe andvStatek of Colorado, have invented certain newand useful Improvements in Dry Closets; and Ido" declare the followingto be a full,"clear, and

f exact description ofthe invention, such as will enable others skilledin the art to which it appertains to make anduse-the same, referencebeing-had-to the accompanying drawings, and' lto the: figures ofreference marked t ereon which form a part of this specification.

My lnvention relates to improvements in dry closets in which the liquorsare separated from the solid residue and 'carried to evaporating-pans,whence the vapors therefrom are' taken up in a suitable lueby theascending products of combustion, while the residue is removed fromtimeto time; and it consists in" the construction, arrangement, andcombination. of the parts of which ii; is composed, as'

' vwill be hereinafter more fully described and claimed.

Referring to theaccompanyin'g drawings, in which corresponding parts`are'designated by corresponding numerals, Figure 1 is aplan Aview of acloset constructed in accordance with my invention', portions ofthe'several plates thereof being broken away. Fig. 2

is an elevation thereof, parts of the front wall being broken away. Fig.3 is atransverse section on line ct bof Figs. l and 2. Fig.

\4. is a detail of the plate forming the bottom o f the` uppercompartment. Fig.5 is a transverse section on line c cl of Fig.'1. Fig.6 is a .longitudinal section of a closet in which a modified form of theevaporator is used. Fig.

7 Vshows a modified form of smoke and urine trough.,

The closet consists of a vault'structure upon which maybe erected asuitable 'form of superstructure, (not f shown,) the vault structurehaving at one end thereof a flue or Stack 3, which is-separated from thelower portion of the vault by ineans of the transverse Wall 4, while alsecond transverse wall,

A v5' of -a little greater-height is constructed within the vaultbetween the said wall .4 and 5o the opposite end wall 6 oft-he vault,which 'openings may be formed the plate. v Aopposite end of the plate 9between the wail ture1(l), whence, thesaid end is led'iorward ononeside'of the .opening to nearthe front:l thereof, where it passes `undera'pulley 22, se

.covering of the' vault, that portion of the said plate between thestack and the transverse Wall 5 being provided with seat-apertures 10,provided with the vrear,wardlyhinged covers A-11. In `the'annexeddrawings I .have shown `but one of'the said seat-openings; but it isevident thatany desired numbe'rof such seat- In the 5 and the end wall 6an aperture'lZ is formed, it being covered by a lidl, the said aperturegiving yaccess "to the evaporating-pan.

Below the plates 9 and above the top'of the walls 4 and 5 a second plate13 is huilt into the wall,eXtending from end to end.` and side to Sidethereof, the said plate 13 sloping sli'giftlyfom front to r ,a,r, andh'ereina-fterI4 will designate the vault space inclosed by the plates 9and 13 the upper compartment.V An

ssl

aperture 14 is formed in the plate 13 beneath the seat-aperture 10 inthe plate 9, the aperture having-its upper end surrounded by a beading1,5, which flares toward the front, a

curved platelG being inserted between the ared ends-of the beading,while a cover 20 is adapted to turn down over the'said aperture 14, itbeing hingedat 'its rear end to the plate 13in the rear o f the saidaperture.' The lower end' of a cord lssecured to the forward end of thecover 2O and passesrearwardly upward and around pulleys 21, set i'n the,top plate 9 in they rear of the `seat-apercured to the plate-9, and hasits upper end secured to the forward portion of the lid 11. It will thusbe seen on raisingv the`lid11 that the .lid 20 will be also raised. Arod'.24 pro-. jectsl from t-he rear wall-of the vault and serves tocarry a helical vspring `Zai-,tile for- Award end of which projects asuilieient distance toward the front of. the vault .to bear upon the lid20 whenthelatter is raised, the

Ksaid spring tending to throw the said lid 20 down and thus to c1ose.the upper lid 11, which will be done immediately upon the pressure rooofthe body being removed Vfrom the lid 11. An aperture 26 is found inthe plate 13 beneath the aperture 12 in the plate 9, the said aperture26 being provided with a lid 27 and beingimmediately above the aperture27 (provided with the lid 28) in the topof the furnace 29.

' As will be seen from Figs. 1, 2, and 5 of the drawings, the furnace 29is composed ofany suitable material and is built within the vault itbeing in the forward portion of the latter v lines in Fig. 2,) also setin the front vault wall,

the end wall 33 of the-furnace being apertured at 34 for the admissionof air directly to the combustion-chamber from the end of the vaultbelow the plate '13, to which the air is admitted by the'aperture 35 in'the end wall 6. A defiector 36 projects inwardly fromthe end wall 33 ofthe furnace above the opening 34 to near 'the opposite wall thereof,while an evaporating-pan 37 projects from the said opposite wall of thefurnace to near the said wall 33, the said pan being slightly above theplate 36, and it will thus be seen that the products ofv combustion toreach the smoke-trough (to be hereinafterdescribed) will be compelled topass ,beneath and over the said pan 37,*thus evaporating the contentsthereof. Oppositely '-disposed ledges 40 are placed upon the transversewall 5 and the end wall 4 at about the level of the top of the furnace,upon which ledges a trough or pan 41,

provided with engaging lips 42 upon its ends, is adapted to slide, thefront wall of the vault being provided with a door 43,through which thepan may be withdrawn when it is desired to remove the solid residue.From the abovedescribed location of the pan it will be seen that it isbeneath the seat aperture or apertures 10, and that it is adapted toreceive the deposits therefrom after they have passed through theaperture or apertures 14. The center of the trough or pan 41, which isat its lowest point, is perforated, as at 44, to permit the passage ofliquids, the perforations being in line and over the combined smoke andurine trough 45. This trough 46, into which the liquids fall, extendsfrom the furnace to the flue 3, it entering the former above theevaporating-pan 37, vto which it is adapted to conduct the liquids whengiven the proper inclination. In the drawings two forms of troughs areshown, the one shown in Fig. 3 having two separate conduits, thelowercovered one 45 for the smoke and the upper uncovered one 45" for theurine, the two being separated by the partition 45c, while iu Fig. 7 aform is shown in which the two conduits are united in one, the trough 41being formed without the partition. may be desired to change the pointof evaporation from the furnace to the base of the As in some cases itstack or flue, at which latter point any de- 7o '-rator in the base offlue, (for which a spout 53 may be fitted to the trough,) while if itrests upon one of the cranks of the enlargement, as shown in Fig. 2, theurine will flow into the evaporating-pan in the furnace.

In order to furnish that portion of the vault which is below the pan 41and .between the walls 4 and 5 with air, a plate 55 is placed within thevault near the bottom thereof and between the rear wall of the furnaceand the vault, thus forming a passage 56, connecting.

` at its opposite ends with the apertures 57 and 58, in the base of thetransverse wall 5 and the end wall 6, respectively.

In Fig. 6 a form is shown in which the sole evaporator 60 is located inthe base of the flue, the urine-trough being given the properinclination for the flow of urine to take place in. that direction only,and a spout 53L is placed upon the -lower end of the trough to conveythe urine into the said evaporator. In this figure the furnace is shownwithout the evaporating-pan, a deflector 36" being used, however, and,as will be noticed, both the evaporator 60'* and furnace are shown to beheated with gas.

The operation of the invention may be summarized -as follows: The lid orcover 11 having been raised, raises with it the under lid 20, and mattermay then drop through the two apertures 10 and 14 in the two plates 9and 13 into the 'pan 41, through the perforations in which the liquordrains in the urinetrough, and thus tothe evaporating-pan in the formeror the base of the stack, as the case may be, the direction of the flowin the, construction shown in Figs. 1 to 5 being dependent upon theposition of the bar 49, as has already, been described, the position ofthe said bar being readily changed'by means of the handle 57 to suit the'choice of the op erator. In any case the. urine is in its passagethrough the trough more or less evaporated, thus reducing to a minimumthe amount lof work to be done .by the evaporatiug-pans,

while at the same time the solids left inthe pan 41 are dried by theheat arising from the' trough, and are thus when the pan is removed fromthe vault to be emptied in a state in which they can be the most readilyhandled. It will also be seen that the constant draft up the flue orstack will keep the air in .all
